A National Registry of Patients With Hepatocellular Carcinoma

The purpose of this research is to study the factors which might cause hepatocellular carcinoma (a form of cancer arising within the liver) and compare these factors in patients from different ethnic groups and from different parts of the United States. The researchers will also conduct a survey of the stage of the cancer (how far advanced it is) and what treatments are used for this difficult-to-treat tumor.
